BOSE SoundDock Portable For sale is a set including the speaker unit, AC adapter, and remote control. There are no instructions or box. Music playback is possible by connecting an iPod, but the battery cover on the remote control is damaged, making it difficult to replace the batteries. Volume adjustment, etc., is possible by pressing the buttons on the side of the body, so there is no problem with the use itself. It is usable except that only the battery cover of the remote control cannot be opened. Please understand that this is a junk item.
